I don't think this list is anything that's truly revealing or revaloutionary. Another probelm I find with this list is the lack of names, other than those out of the league. Some of those listed are out because of injury, some are even dead. You can never foresee these events, so in those instances I don't think that is a fair evaluation.
If there were names identifying the players who failed, I would venture to guess at least a couple of them who were considered failures by the teams who drafted them found success somewhere else because the system fit their skills.
Of course, you do have some reccurrent floppers, and it is usually the same teams you see associated with these picks...like the Lions, for instance.
It's always better to look at a team's, and their GM's draft history to see who is successful, and who is not. You can always argue who's the best, and the following list will be open to arguement, if you're talking soley about draft picks. However, certain teams utilize various methods to stock their teams with players. If you're talking draft pick success, the 1st team on this list does not belong...however, their methods of judging talent and building their team is successful, and has been over the course of time, so yes, they belong. Anyhow, it's an interesting read, and also mentions some "up and comers" who are on the verge of being known for being elite in their ability to judge talent, and build a team.
